We have a new pool, finished in September this year. The pool builder went out of business and left us without doing a startup on the new water. I need to know how to regulate the PH. It is too low.
My husband added chlorine stabilizer and now thinks that is affecting the PH. Yes? Please let me know what to do. Again this is new pool/water. The pool is Vinyl, about 15000 gallons.
Thanks.

Stabilizer will not affect he PH of your water. If it is low I would start with adding a pound of soda ash or ph increaser. Add it to the deepest part of your pool. Check your PH level again in a day. Certain things will affect your Ph like rain can bring it up or down adding chlorine will usually bring it up because the pH in chlorine shock(calcium hypochloride) is around 11. You want your PH to be around 7.2 to 7.6

If you go to a Bio-guard pool chemical dealer they shold offer a free water test and analysis. If not try to get a test strip that also tests for Total Alykalinity, this acts as a buffer for ph bounce from: rain, bather load, chlorine shock. Having a professional water analysis and adjustment will make water maintenance much easier.
